Turn around...don't drown when encountering flooded roads. Most flood deaths occur in vehicles. Additional information is available at www.weather.gov/phi. The next statement will be issued this morning at 1130 AM EDT.

As mid level clouds continue to clear out this morning, areas of fog have started to develop across the region. Some of this fog will become locally dense and reduce visibility to one mile or less at times. Motorists should exercise caution and be prepared for rapidly changing visibility when driving. Conditions will gradually improve by mid-morning.
